Notes:

1. Transmitter consists of 12 lasers operating at a maximum rate of 10.5Gb/s each.

2. Even if TDP is <0.9dB, the OMA min must exceed this value.

3. RIN is scaled by 10*log (10/4) to maintain SNR outside of transmitter.

4. Receiver consists of 12 photodetectors operating at a maximum rate of 10.5Gb/s each.
